Hydraulic fracturing, Also Known As Fracking, is a Well stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of ‘fracking fluid’ (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures op

A team of scientists believes they have discovered the first extraterrestrial protein known to humanity. Using a new analysis technique, the researchers claim to have found the out-of-this-world discovery inside a meteorite that fell to Earth some 30 years ago.
